Detail of working head.
Remove the seal using a suitable
tool. Wash and clean the piston
and interior of the head with
isopropanol.
Usually it is not necessary to
exchange the seal in washing
heads, but in case it is needed,
follow the same steps as with
working heads.
Wet new seal in isopropanol and
place it on the piston carefully. The
spring is facing toward the head.
Pushing the head back on the
piston must be straight.
Leaning
the head to sides may cause
seal damage.
Fasten the screws and mount
tubing and capillary back on their
place.
After seal replacement are the steps for mounting the same as during dismounting, but in
reverse order.
Pushing the head with new seal back on the piston must be straight.
Leaning the head to
sides may cause seal damage.
Caution:
Screw in the left and right screw alternately into the heads of each blocks.
Each screw must be screwed with the same number of turns.
